I found an error in my configs and fix it but the problem remains. In beans.xml I've added section with authenticator name:

<security:IdentityImpl>
	<s:modifies/>
	<security:authenticatorName>jaasAuthenticator</security:authenticatorName>
</security:IdentityImpl>

To make it working I've added patched version of seam-security (as recommended on guvnor forum). And now I see login window and even can login, but after it I still get the same error messages like in my previous message.
